BALTIMORE, MD—The National Weather Service has issued a Tornado Watch for Baltimore County.

The watch will remain in effect until midnight on Halloween night.

A Tornado Watch means that conditions are favorable for the development of tornadoes in and close to the watch area. Their size can vary depending on the weather situation. They are usually issued for a duration of 4 to 8 hours. They normally are issued well in advance of the actual occurrence of severe weather.

During the watch, residents should review tornado safety rules and be prepared to move to a place of safety if threatening weather approaches.
